Agree with the first part of your answer, but not sure what you mean by this second part.
There is dedicated hardware for it, then there are solution using your generic gpu (ex Nvidia RTX Voice), then there are solution using your generic cpu (ex whatever the name of the one discord desktop client provides).
That appears to be a "noise canceling" microphone adapter. It doesn't even claim to offer headphone noise canceling, it's just for microphones. There are two dots that might possibly be microphones for active noise cancellation, but I suspect that they would be too far away from your face to be effective. Most likely there is just a DSP inside that tries to filter out background noise heuristically.
there's not too much detail on that page but what I see is that it "reduces EMI interference" from a mic. that's a different thing than noise cancellation (remove the noise from your background so that you hear the audio better)
isn't that different? i thought that's noise isolation that runs using a Neural Net. i don't think it's as real time as you'd need for noise cancellation
